I purchased Earthgro topsoil also from homedepot to find the difference. When I was mixing the water and with earthgro soil I noticed Greasy kind of substance sticking to Hand. Is this natural?

Wet clay is geasy feeling. Is that what you're finding? Compare it to the block of clay you bought seperately.

Just passing on something I learned when searching for clay:

AMACO (American Art Clay) is a common brand found at crafts stores in the USA, such as A.C. Moore and Micheal's. I emailed their technical support to ensure some of the stuff I found would be fine for aquarium subtrate use. AMACO warns that a lot of their clays found in craft stores have preservatives added and they don't recommend using those in aquariums. Two AMACO clays that may be found in craft stores that didn't have preservatives are "Sedona Red Casting Slip No. 67" and "Magic Mud".

The AMACO Terra Cotta Air Dry clay I had found in 10 and 25 pound boxes at my local A.C. Moore were not recommended because of preservatives. They did have Magic Mud but it was a white clay, so it's likely is not iron rich enough for Aaron's MTS recipe.

I live in an area where wind is heavy most of the time in my patio because of the landscape. drying the topsoil on the floor causes huge mess because of the wind and also I am afraid fine soil will be blown away by the wind which will spoil the purpose of topsoil. thats the reason I opted for tank.

I already emptied the tank couple of times so I believe with just soil and 5 inches of water above the soil is not that hard to empty out the water.

Once the minerization is completed I will move the soil to bucket and move the aquarium into the home. This is what my plan is. but If I have to follow the process and use only the sheet I have to dry this soil in my friends place.
The topsoil will kinda clump together when it dries out so I've yet to have an issue with it blowing away and I set mine out in a fairly windy area as well. One important part is to have it in an extremely thin layer so that it goes through the drying process really well (and much faster) each time.

I use heavy plastic sheeting material and spread it out with a rake.

As far as the clay and other materials go, I just ended up buying them in bulk amounts so I have a ton to work with, but it justified the cost of having it shipped in.

I know you explained pretty clear but when I started the process of mineralizing right then the questions started hitting me for each and everything in the list below.
Cheap topsoil
Pottery clay
Dolomite
Muriate of potash

The Aquarium I am currently working on is 90 GAL (48 Lx 18 W). So please help me with the quantities if I am putting toomuch or too low.

Topsoil: I got the Topsoil from peterose. Usually this store sell them in tones but the guy let me fill the 5GAL bucket pure topsoil(Without any mulch/peatmoss mix) for free. I noticed minimal organic stuff in it. I started mineralizing the soil. During the process when I dump the muddy water, I noticed Fine soil(Creamy texture) is getting dumped with muddy water. According to my understanding this creamy texture soil is pure soil. When this creamy texture soil dried its turned out like soft powder. The soil sitting in the container bottom has sand like texture that you feel in the beach. The questoin I have is Do I need to keep this creamy texture soil along with sandy texture soil or just sandy texture soil or just creamy texture soil?

Q 1) Which texture soil do I need to keep?

Q 2) 5 GAL bucket Topsoil is that enough for 90 GAL Tank ?

Pottery Clay: I got 2.5 pounds of gray color Pottery Clay for 2$. Not sure whether that is the right clay for this project or not. see the Picture
Q 3) I am not sure also whether the picture helps or not. if Helps Is this the right pottery clay?


Dolomite: Not sure whether this is the right thing I purchased or not. Please see the pictures.
Q 4) Is it the right one? if so howmuch do I need to put in 90 GAL Tank?

Muriate of Potash: Not sure whether this is the right thing I purchased or not. Please see the pictures.
Q 5) Is it the right one? if so howmuch do I need to put in 90 GAL Tank?

I really appriciate your help on this
I know you were talking to aaron but hopefully I can help answer a few of these.
A1) I sift the soil several times so its a fluffy light texture.
A2) a 90g, assuming it has a 48x18 footprint, would need about 30lbs of soil, give or take, to make a 1/2-3/4" layer. This is based on a very rough estimate that approx 5lbs cover a 1sq ft area.

A3) As long as its natural and not a polymer clay it will work. It's hard to say just by the looks. Usually when its labeled as pottery clay, it is the right stuff, modeling clay is not. However I would still do more research through the source.

A4) Actually, no. Check the analysis and I think you will find that it probably has calcium oxide in it.

That being said, though, I've used this type of pelletized lime in setups and had no noticeable effects because of it. The amount being used is very minute, mind you. A light dusting or sprinkling at best. The best kind to use (imo) can be found in powder form either through a pottery supply or at a vitamin supply place. Vitamin shoppe has it in powder form so you don't have to crush the pills.

A5) yes that is the right stuff. A light dusting is all it takes.

I am at a halt on my collection of materials, since I can't get Muriate of Potash in Canada, its been banned.

Am I correct to assume, that it is the same as Potassium Chloride, then assume, that I could also use Potassium sulphate, I did some looking and it seems that its better for the plant roots as the sulfate form. But is it worse for the livestock? Would it substitute if I could find it.

Also, what % of potassium am I aiming for, 40%?

I could order Lab grade potassium chloride from a chemist supplier, but I'm not sure if that will be the right stuff either.

also, when laying out the soil to dry, is it alright to strain the water? or do you want it to evaporate (into) the soil?

Hi aaron I was wondering where you got the 3M Colorquartz T-Grade Black Sand and how much it costs, I like the idea of the soil I'm going to try it for my first planted beta biotope, thanks for the idea by the way. and of course the instructions.

Would this stuff be suitable for using dry for more contoured substrates? Would it hold a slope?

would using garden soil (rinsing with water) which has no additivies skip the whole wet/dry cycle process? since this process is to remove organic matter, i would assume that soil which has been laying in the garden for a month would be well removed of organics
